The combination with e hinged ferry bridge, of means for mooring s fierryboss thereto endfor equalizing the height of the bridge and boat, comprising a Iiiiing element having one branch connected both to said bridge and to said boat to exeri; e bori zontai force on the boat tending to 1d the latter egeinst the bridge and a iifieg force on the bridge, and a second" breaioli connected directly to the boat end. adapted to exert a lifting force on the Easier.

2. The combineision with e hirige bridge, of means for mooring s ferrybos thereto and for menipuletirigqibe bridge; comprising a, pulley secured to the free end of the bridge, a stationery superssruesure, a pulley mounted thereome oouniaer-bsifinoing Weight, and a flexible element running over the last mentioned pulley we having one end conneceed to said counter Weight and the other end deoending from said overhead structure and bifurcated, Wiiiil one branch of said bifurcated end passing wider the first mentioned pulley and secured to the boat and the other brerioh attached dire-oily to the boat. v
